Most of the energy costs spent to keep a East York home warm in the winter and cool in the summer end up leaving through the attic. In the summer, the sun’s heat pours in through the attic and in the winter, warm air rises past the ceiling and out of the home. Saving on energy costs starts in the attic, but how much insulation is enough?

Although spray foam insulation as we know it today truly emerged in the 1980s around the East York area, spray foam actually has its roots several decades further in the past, beginning with the development of polyurethane foam in the 1940s by Otto Bayer. Otto Bayer, an industrial chemist, actually began working with polyurethane in Germany during the late 1930s. This technology was brought to the United States in the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate created from the partnering of two chemical industry giants, Monsanto and the Bayer Corporation.
Spray Foam Material Handling and Storage
An energy efficient home is an environmentally sound home and to achieve energy efficiency insulation is vital. It must be used liberally, and it must be properly installed. There are all sorts of insulating materials, and their green credentials may vary.
The most common is Pink fiberglass Batts which are by no means the worst from an environmental perspective but they aren't the best either. Fiberglass itself is chemically inert, but the glues and backing materials that provide structure to the batts can release dangerous fumes and there is some concern that minute particles of fiberglass can filter into living spaces, presenting a health risk. Rigid polystyrene panels, another popular choice, are made from petrochemicals which are flammable and emit toxic fumes when burned.
Misconceptions about Cellulose:
1: Prone to mold and insects; Cellulose Fiber is treated with two non-irritant, non-toxic, safe to handle allergy free agents; Borax and Boric acid which make it vermin resistant.
2: Fire retardant chemicals disappear in 5 years; The most exhaustive study and technical literature review concluded it would take 300 years to do so and only under continuous harsh conditions of 100% relative humidity and 70 degrees Celsius.

Home Insulation - Is It Cold Outside?
Movement of air in and out of a home can be a leading cause of escalated energy bills. Air can enter your house through holes, cracks and crevices. You can stop unconditioned air from entering your home and indoor conditioned air from escaping outside by adding an advanced insulation system to achieve optimal building performance.
As the days begin to warm, your equipment starts to work more frequently, and the purchasing of material increases, there grows a responsibility to the material components. There are two core aspects to properly maintaining the PMDI (ISO) and Polyol components of spray foam insulation, Processing and Storage. There is no single constant for all types of material, but there are some general guidelines and recommendations that can be applied to most types of SPF insulation.
PMDIs, the A-component, and Polyols, the B-component, are complex materials that need to be stored properly, especially during the warm months of summer. Common temperatures for storage typically start around 60oF to 70oF and top off in the vicinity of 100oF. It is ideal to store materials in a well-ventilated and climate controlled area, yet not everyone has accessibility to such a facility. Knowing your specific manufacturer's recommended storage temperatures and watching for the bowing of drums are vital to ensuring the proper performance of your product when you begin to process and apply it.
On the material side, the physical drum temperature and preparation of the material are key steps in a successful application. Many open cell spray foams require a process of agitation and/or recirculation before any spraying begins. Drum temperatures need to be maintained at the manufacturer's recommended levels, which typically land around 75oF. Proper drum temperature is one of the factors in producing quality, high yielding spray foam.
Always consult with your manufacturer before spraying any SPF products to make sure all recommended pressures, temperatures, settings, and other conditions are met.
